ATTINY12L-4SC

Overview

The ATTINY12L-4SC is an 8-bit microcontroller based on the AVR RISC architecture, manufactured by Microchip Technology. It features 1K byte of Flash program memory and 64 bytes of In-System Programmable EEPROM data memory. The device operates within a voltage range of 2.7 V to 5.5 V and supports clock speeds up to 4 MHz. It includes 32 general-purpose working registers, six I/O lines, an 8-bit Timer/Counter, an analog comparator, and a programmable watchdog timer. The component is housed in an 8-lead Plastic Gull-Wing Small Outline (EIAJ SOIC) package.

Feature Summary

• Executes powerful instructions in a single clock cycle for high throughput efficiency
• Integrates nonvolatile Flash and EEPROM memory with programming lock security
• Supports low-power Idle and Power-down modes with pin change wake-up capabilities

Applications

• Embedded control applications requiring low power consumption
• Battery-operated systems utilizing internal RC oscillator
• Simple peripheral monitoring using analog comparator and interrupts

Procurement Notes

Verify that the ordering suffix 'SC' corresponds to the specified industrial temperature range and SOIC package configuration as defined in the official Microchip ordering information tables. Confirm RoHS compliance status if required for specific manufacturing standards. Ensure compatibility with existing SPI programming interfaces for in-system programming.

Selection Notes

Select this component when a balance of moderate processing speed and low power consumption is required. The ATtiny12L-4 variant is suitable for applications operating between 2.7 V and 5.5 V where external crystals are not desired. Consider the available I/O lines and memory size against application requirements before choosing over higher-speed or larger-memory variants.

Part Context

This device belongs to the ATtiny11/12 family of 8-bit microcontrollers. It shares the core AVR architecture with variants like ATtiny11L-2 and ATtiny12V-1 but offers distinct voltage and speed specifications. The family is characterized by its compact size, RISC efficiency, and integrated nonvolatile memory technologies designed for cost-effective embedded solutions.

Replacement Considerations

Direct substitutes include other ATtiny12 speed grades such as ATtiny12-8 or ATtiny12V-1, provided voltage and frequency constraints align with the design. Cross-family replacements from the ATtiny series may require firmware adaptation due to differences in peripheral availability and register configurations.
